I installed squeeze (amd64) in a QEMU VM using one of the daily builds:
"To install Debian testing, we recommend you use the daily builds of
the installer."
This worked fine -- the only problem was slow download rates for the
installer .iso image,
but since the image is small that wasn't a huge deal. I'll be using
squeeze to look for problems with things I use (SageMath, R, SciPy,
Java, Fortran, TeX, hdf4+5, netcdf 3+4).
First observation:
memory requirements seem high. Installing with 256M failed, and I was
shorton time, so I installed with 1G (host machine has 8G), then tried
booting with 256M and the system hung (probably in grub2) after
display a single underscore. Usually VM's are distributed with a
minimum memory setting and you increase the setting if you need more.

Grub2 is based on a Japanese boot loader called PUPA -- one of the goals is
internationalization. Grub Legacy may have been fine for those of us who use
English, but the only way to support the rest of the world was "redo
from start".

I just let the installer use the single partition configuration --
it dot not offer to use ext4.
